Ok....i've got a product page that will access data and images. I can use the traditional Database/filesystem way........or i've recently used the XML/filesystem and it seems to work schlick too.
My question is which is better? What are the drawbacks?
Also if the XML route is sufficient.....would i use 1 big honkin XML file..or would it be more beneficial to break each product lisitng into its own XML file? (is there a potential file locking issue here???) I'm just worried about potential large traffic issues down the road (when the site hits it big! )

Hope all is clear as mud.

Thanks all.
